Enum librashader_reflect::reflect::semantics::TextureSemantics

#[repr(i32)]
pub enum TextureSemantics {
    Original,
    Source,
    OriginalHistory,
    PassOutput,
    PassFeedback,
    User,
}

Texture semantics relate to input or output textures.

Texture semantics are used to relate both texture samplers and *Size uniforms.

Variants

Original

The original input of the filter chain.

Source

The input from the previous shader pass, or the input on the first shader pass.

OriginalHistory

The input frames from previous frames.

PassOutput

The output from previous shader passes in the same frame.

PassFeedback

The output from previous shader passes in the previous frame.

User

A user provided lookup texture.

Implementations

impl TextureSemantics

pub fn size_uniform_name(&self) -> &'static str

Get the name of the size uniform for this semantics when bound.

pub fn texture_name(&self) -> &'static str

Get the name of the texture sampler for this semantics when bound.

pub fn is_indexed(&self) -> bool

Returns whether or not textures of this semantics are indexed or unique.

Only Original and Source are unique, all other textures can be indexed.

pub const fn semantics(self, index: usize) -> Semantic<TextureSemantics>

Produce a Semantic for this TextureSemantics of the given index.

Trait Implementations

impl Clone for TextureSemantics

fn clone(&self) -> TextureSemantics

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TextureSemantics

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for TextureSemantics

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TextureSemantics

fn cmp(&self, other: &TextureSemantics) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<TextureSemantics> for TextureSemantics

fn eq(&self, other: &TextureSemantics) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<TextureSemantics> for TextureSemantics

fn partial_cmp(&self, other: &TextureSemantics) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
